Varifold folding propellers have taken the market by storm. Regularly fitted by such notable yacht building names as Baltic, Swan, Wally, Moody and Oyster, the complete range of Varifolds has a model for cruiser racing and racing yachts of every size. Varifold is revolutionary in design and brings a revolution to the yachts they are fitted to. Radical reductions in noise and vibration and excellent performance under engine, both ahead and astern, are the result of the propellers unique design. Varifolds have proper helical pitch distribution, including pitch reduction towards the blade tip. This pitch reduction %u2018unloads%u2019 the blade tips and, combined with the skewed blades, greatly reduces noisy pressure pulses against a yachts hull. While some other folding propellers have a helical pitch shape, few have proper sections or pitch distribution. None, put all these requirements into a complete package, except Varifold.
So advanced is Varifolds design that a 4 blade version has successfully been fitted to a yacht with a 750hp engine, we believe that would have been an impossible task for any other folding propeller. Each Varifold, whatever its size, is built to the same extremely high specification from a nickel-aluminium-bronze alloy which guarantees great strength and high corrosion protection. Cruiser racing and racing yachts can now get the best of both worlds; a folding propeller that combines low drag when sailing, with efficient and quiet power when motoring. Oh, and by the way %u2013 Varifolds open in reverse, and not just sometimes!

By now everybody knows about the function of the folding blades propeller for sailing hulls is:
TO REDUCING THE PROPELLER DRAG DURING SAILING
(propeller drag is reduced about 90% compared to the traditional two fixed blades propeller).
The opening operation is automatic and is caused by the centrifugal force, increasing according to the engine revolution. In forward gear the pressure on the blades allows a performance equal to the fixed-blades propeller.
During this opening phase a quick acceleration of the engine is not advisable, and we recommend to make it
smoothly and gradually.
Even at low revolutions the centrifugal force is enough to opening the blades.
When the engine is off, a forward speed of 1 to 2 knots generates sufficient water pressure for the blades to close.
Reverse gear has always been the main problem for folding blades propellers.
Mainly due to the water pressure acting in opposition to the blades opening and the lack of a support point for the blades on the hub, only partially open, and the blades float, causing an unstable and insecure condition when maneuvering.
In order to avoid this inconvenience we studied and tested special blade sections that allow the blades to remain fully open during reverse operation with positive maneuvering results.

It's no coincidence that carbon fibre is used in aeroplanes. Carbon composite combines stiffness and strength with low weight. Selden low-weight carbon spars have accentuated longitudinal stiffness. This means that forestay tension can be substantially increased. All experienced racing sailors know what this means in terms of increased performance. The combination of greater stiffness and reduced weight will bring you beyond the speed limits.
